ABSTRACT:
A strainer drum has a series of axially juxtapositioned, apertured carrier discs which define axially spaced, alternating, circumferentially extending crests and roots. The carrier discs support a prefolded one-piece filter fabric of the weft-and-warp type which is wrapped substantially 360.degree. around the discs and which conforms to the crests and roots defined by the carrier discs. The wefts and warps of the filter fabric are oriented obliquely with respect to the drum axis.
